The titles says it all, but to elaborate a little.
Poor operations at MOT gives them low operating margins. In some places, MOT runs on negative operating margins.
MOT has room to grow in the high margin product segment of high end handsets, but it doesn't mean it can compete once it enters. Seems risky.
If MOT wants to stay in the low and mid market segments, it needs to look into places like China, India, Eastern Europe and Africa. Those are all areas that Nokia has excelled in. Like moving into the upper end market, even if MOT whole-heartedly enters those markets, it doesn't mean it can compete.
